Title
wifi: wcn36xx: fix channel survey memory allocation size
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix channel survey memory allocation size KASAN reported a memory allocation issue in wcn->chan_survey due to incorrect size calculation. This commit uses kcalloc to allocate memory for wcn->chan_survey, ensuring proper initialization and preventing the use of uninitialized values when there are no frames on the channel.

This matches the WiFi frame-injection = Adjacent guidance.\nAC:L - The attacker chooses the channel (non-DFS 5 GHz UNII-3 channels 149-165 map to the furthest out-of-bounds offsets), and client devices scan those channels automatically and repeatedly; the uninitialized-memory disclosure via survey dump is deterministic on every boot.\nPR:N - `wcn36xx_update_survey()` runs on every frame at RX time, before mac80211 authentication/association, so an unauthenticated attacker with no credentials on any network triggers it. The corresponding read path is exposed through `NL80211_CMD_GET_SURVEY`, which carries no admin-permission flag and is dumpable by any unprivileged local user.\nUI:N - No victim action is required \u2014 wpa_supplicant/NetworkManager background scanning hops through the affected 5 GHz channels automatically, and a device merely operating on such a channel writes out of bounds on every received frame.\nS:U - The heap corruption and information disclosure are confined to the kernel\u0027s own memory and security authority, with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - `wcn36xx_get_survey()` reads up to 38 bytes past the 39-byte allocation and returns the values to userspace via the unprivileged nl80211 survey dump, and the missing zeroing leaks uninitialized kernel heap contents; the out-of-bounds access also provides a lever for broader disclosure.\nI:H - Received frames on high 5 GHz channels write attacker-influenced RSSI/SNR bytes at offsets 64-77 of a 39-byte allocation, corrupting the adjacent slab object \u2014 a heap out-of-bounds write, which scores High per the guidance.\nA:H - Corrupting neighbouring heap objects (and tripping KASAN/redzone or slab metadata checks) causes kernel oops or panic, and the write is triggerable repeatedly by any nearby unauthenticated transmitter."

This matches the WiFi frame-injection = Adjacent guidance.\\nAC:L - The attacker chooses the channel (non-DFS 5 GHz UNII-3 channels 149-165 map to the furthest out-of-bounds offsets), and client devices scan those channels automatically and repeatedly; the uninitialized-memory disclosure via survey dump is deterministic on every boot.\\nPR:N - `wcn36xx_update_survey()` runs on every frame at RX time, before mac80211 authentication/association, so an unauthenticated attacker with no credentials on any network triggers it.

the out-of-bounds access also provides a lever for broader disclosure.\\nI:H - Received frames on high 5 GHz channels write attacker-influenced RSSI/SNR bytes at offsets 64-77 of a 39-byte allocation, corrupting the adjacent slab object \\u2014 a heap out-of-bounds write, which scores High per the guidance.\\nA:H - Corrupting neighbouring heap objects (and tripping KASAN/redzone or slab metadata checks) causes kernel oops or panic, and the write is triggerable repeatedly by any nearby unauthenticated transmitter.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"29696e0aa413b9d56558731aae3806d7cff48d36\", \"lessThan\": \"ae68efdff7a7a42ab251cac79d8713de6f0dbaa0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"29696e0aa413b9d56558731aae3806d7cff48d36\", \"lessThan\": \"e95f9c408ff8311f75eeabc8acf34a66670d8815\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"29696e0aa413b9d56558731aae3806d7cff48d36\", \"lessThan\": \"64c4dcaeac1dc1030e47883b04a617ca9a4f164e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"29696e0aa413b9d56558731aae3806d7cff48d36\", \"lessThan\": \"34cd2817708aec51ef1a6c007e0d6d5342a025d7\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"29696e0aa413b9d56558731aae3806d7cff48d36\", \"lessThan\": \"6200d947f050efdba4090dfefd8a01981363d954\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/wireless/ath/wcn36xx/main.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.18\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.18\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.129\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.76\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.13\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.13.2\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.13.*\"}, {\"status\": \"unaffected\", \"version\": \"6.14\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/wireless/ath/wcn36xx/main.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/ae68efdff7a7a42ab251cac79d8713de6f0dbaa0\"}, {\"url\": \"https://git.kernel.org/stable/c/e95f9c408ff8311f75eeabc8acf34a66670d8815\"}, {\"url\": \"https://git.kernel.org/stable/c/64c4dcaeac1dc1030e47883b04a617ca9a4f164e\"}, {\"url\": \"https://git.kernel.org/stable/c/34cd2817708aec51ef1a6c007e0d6d5342a025d7\"}, {\"url\": \"https://git.kernel.org/stable/c/6200d947f050efdba4090dfefd8a01981363d954\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nwifi: wcn36xx: fix channel survey memory allocation size\\n\\nKASAN reported a memory allocation issue in wcn-\u003echan_survey\\ndue to incorrect size calculation.\\nThis commit uses kcalloc to allocate memory for wcn-\u003echan_survey,\\nensuring proper initialization and preventing the use of uninitialized\\nvalues when there are no frames on the channel.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.129\", \"versionStartIncluding\": \"5.18\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.76\", \"versionStartIncluding\": \"5.18\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.13\", \"versionStartIncluding\": \"5.18\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.13.2\", \"versionStartIncluding\": \"5.18\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.14\", \"versionStartIncluding\": \"5.18\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:47:16.997Z\"}}}",
